74 : EXPEDITION OF THE “ALBATROSS,” 1899-1900. 
but it being on the line of the equatorial current, it also shows the effect 
of the increased supply of food carried by a great oceanic current. This 
haul is a striking contrast to those taken farther south to the southeast 
of Tahiti at about the same depth, but outside the range of any great 
current. In that district we found practically nothing living on the red- 
clay bottom. It seems natural to infer that the lines of migration of the 
deep-sea fauna of the tropical Pacific must have been along the track of 
the equatorial current. 
The trawl contained three species of Holothurians, one of which was 
bright carmine; a number of siliceous sponges, among which a small 
Hyalonema with its Zoanthus attached to the bundle of spicules; a few 
colossal spicules nearly as thick as a lead pencil; alot of the Neusina we 
collected in 1891 in the Panamic region; two species of Actiniew, one of 
which a brilliant carmine, the other heavy, thick-skinned, whitish, both 
found attached to siliceous spicules; a species of Archaster, and a good 
specimen of Linopneustes; a peculiar fish with a long head and_pec- 
toral fins, spread vertically. upright across the flanks, and having two 
long caudal filaments; a few manganese nodules, and a number of small 
sharks’ teeth; a couple of specimens of Scalpellum, and what I took to 
be fragments of the interesting Ascidian Octacnemus of Moseley. Some of 
the large siliceous spicules must have been 24” long. Also a small white, 
thick, stiff-armed Ophiuran; some worm-tubes built up in part of mud and 
of siliceous spicules; two excellent specimens of Terebella, a Pectinaria-like 
worm, and great numbers of Radiolarians collected from the intestines of 
the Linopneustes; two specimens of Amusium; a Gasteropod; a Webbina 
attached to Neusina; a small Plumularian; a fragment of a Polyzoan ; 
and a Kucopia which found its way into the net near the surface. The 
list of the contents of this trawl-haul is quite sufficient, when contrasted to 
that of the haul at Station 173, to emphasize the contrast between locali- 
ties in the wake of the great equatorial current and those outside of 
its influence. 
At Station 25 we lowered the beam-trawl in 830 fathoms, lat. 8° 48’ S 
ied 
long. 139° 48° W., in the channel between Nukuhiva and Washington 
Islands, the bottom being Globigerina ooze and volcanic mud. The trawl
